Appli ati fil d March 7, 1906. Serial No. 304.725.

T 0 all whom it mag concern:

Be it known that 1, WILLIAM OTTAWAY, a citizen of the United States, of Aurora, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Inlet-Valve Mechanism for Explosive-Engines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in explosive engines and refers more specifically to an improved admission valveby which is controlled the admission of the explosive mixture to the engine cylinder.

Among the objects of the invention is to simplify the construction of the valve and to pro uce a valve which may be readily removed from the cylinder head and replaced thereon.

A further object of the invention is to provide a casing or shell for the inlet valve of such construction that it may be angularly adjusted so that its admission opening or branch may be turned to any angular position desired.

A still further object of the invention is to provide an improved means for unseating the valve pre aratory to starting the engine, or at any other time when the inlet valve. tends to stick on its seat.

The invention consists in the matters hereinafter set forth and more particularly pointed out in the ap ended claims.

In the drawings igure 1' is a vertical sectional view of the head end of an explosive engine cylinder, showing my improvled inlet ig. 2 is ato plan view of the seat ring of the valve mec anism. Fig. 3 is a side elevation thereof. Fig. 4 is a top plan view of aspecially formed locking ring by which the seat ring and also the valve casing or shell are locked in place. I Fig. 6 is a side'elevation of the assembled seat ringfvaive closure or disk and the spring for holding the valve disk against its seat.

As shown in said drawings, A designates the cylinder of an explosive en inc and A the head thereof. The head A is formed at one side of the cylinder to provide a casing A in which is formed the ignition chamber a, and B' O designatefrespectively, the ex- Fig. 5 is a side eleyation thereof.

haust and inlet valve disks which open towards said ignition chamber. ing A is extended downwardly at the side of the cylinder to form an exhaust passa e A which communicates with the ignition 0 am- The said casher a through a port controlled by the valve disk B.

D designates the inlet valve casing or shell 1 the cylin er head.

The ring is provided between its ends with an exterior annular flange E which opposes an upwardly facing shoulder a insaid 0 ening of the extension, and said ring is he (1 in a place by means of a locking ring F which surrounds the upper end of the seat ring and bears against the flange of'the said ring, and

is exteriorly screw-threaded to engage the interior screw -threads of said opening. Preferably, a gasket or acking ring 6 is interposed between said ange E of the seat ring and the shoulder a of the casing A Rising from said rin and formed integral with an a ertured we 2 thereof is a short, vertical tu e or nipple E upwardly through which extendsthe stem 0 of the inlet valve disk and which constitutes a guide for said stem. The said stem extends-beyond the tuloe-or nipple E and is rovided at its upper end with a short flange sleeve C constltuting a shoulder, between which and the a ertnred web of the seat ring is interpose an ex ansively acting spring E which acts to ho d the inlet valve disk C against its seat. The said sleeve C is fixed to the upper end of the stem by means of a short key 0 extending through a transverse opening'inthe upper ,end 0' the stem.

The shell or casing D is confined between the cylinder head and a nut G having screwthreaded engagement with a ring E which is rigidly connected with the locking ring F by means of bars ff, preferably made intevalve casing D is providid at its inner end with an annular bearing surface which rests or fits upon the said annular seat. In the particular construction shown, in the draw'-' mgs the said casin D is provided at its inner margin with av cy indric extension d 'Which fits within the opening in. the cylinder head and also with an outwardly extending annular flange d which bears against an annular, outwardly facing surface surrounding said opening, The valve' casin or shell -D is provided at its outer end with a concentric opening, withinwhich is located the outer 1 ring F, that is rigidly connected'with or forms an extension of the locking ring, as

,before stated. The said nut G has screwthreaded .enga ement with said outer .ring F preferably y means of external screwthreads on said n'ut engaging internal screw- 5 threads on'the said ring. Said nut G is provided with an outwardly extending annular flange g which is ada tedto bear against an. annular outwardly acing bearing surface surrounding the openin in theouter end of the shell or casing, en the said nut is tightened against the outer end .of said shell or casing the latter is clamped between said nut and the annular seat oil-the cylinder. The said'ring F, with the outer ring F and the bars f connecting said ring, sofaras the function of these parts in clamping the valveshell or casing. to thecylinder is concerned, constitutes, with the nut G, clamping means located inside of, or'extending 40 'throu h, the valve shell or casin' and con-. necte with, or secured to,-the cy inderwall inside of the annular casing seat thereon; it

being obvious that, iii-the particular constructionof such clamping means illustrated in the drawings, the ring F with its extension, constitutes one clamping member, and the nut the other clamping-member, of such clamping-means i The clamping of the valve cas' or'shell 5 D between the'flange g of the nut and the cylinder head, in the, manner escrib'ed, aflords means by which the shell may be readily removed,, thereby pennit'ting' convenient access to the locking ring to remove thesa'me from the. seat r111 The valve disk and its stem are removab e'together, as

the parts are herein shown as'assembled- ,Suqh removal'of thecasin D exposes the, valve seat; to 'view and lea age in the valve, ocean-be rea ilyidetecteda The construction described}; permits the valve casing or shellfDTto'be an direct the branch 1 thereof in any.conven-' ient direction for connection with the car- .65 bureting device. When said casing has :rigidly inits adjusted position.

,seat surr larly adjusted so as to been adjusted to the required angular posi tion, it may be locked rigidly between the flan e g of the locking-nut G and the head of t e cylinder, whereby the casing is held As a'further'improvement, novel means are provided for unseating or forcing the valve disk off its seat preparatory to starting the en ine, or to release the disk if it should sti'c or adhere to its seat; 5 I

My improvements consist in a plunger H e opening in the nut G, in axial alinement with the,

stemkhsaid' normally springpressed to h old it away from the stem of the go 4 valve disk and is forced inwardly against the end of the stem torforce the valve disk off its seat. As herein shown, said plunger extends through a two-part sleeveconslstfi ing of an outer part I and an inner gfirt P. 35

SaIdinner part extends outwardly ough an opening in the nut G and has screwth-readed engaglement therewith and the outer member fits .over and screwthreade'dengagement with the upper end of 9 said inlner par-t.
